HELICAL ANTENNAS
AND RF FEEDS
HELICAL ANTENNAS
HRP series Helical Antennas are available for circularly
polarized RF systems including:
DATA LINK,
MOBILE SATELLITE,
BASE STATION,
FTS (FLIGHT TERMINATION SYSTEM), and
SIGNAL MONITORING APPLICATIONS.
Helical antennas are available for use in ground-based
systems, shipborne platforms and airborne applications.
Circularly polarized Helical antennas are ideally suited and
regularly deployed for satellite communication, control and
telemetry systems. Several models also include the beam tilt,
optimized for SATCOM applications.
HRP – 88
HRP – 12
Our innovative helical antennas for Remote Monitoring Station
(RMS) applications (see Models HRP-15-RMS and
HRP-15-RMSS provide a cost-effective solution to receive RF
signals from a desired satellite while discriminating against the
adjacent satellite. Carefully balanced elements result in
isolation of at least 20dB between two signals from adjacent
satellites. HRP-15-RMS effectively replaces two 3.7m L-band
reflector
antennas
which
have
equivalent
angular
discrimination.
HRP–15–RMS
CPA series Helical Arrays are comprised of multiple helical
antenna elements for high gain applications.
High-gain and high-power CPA antennas are designed for
Flight Termination Systems. These antennas interface to highvelocity and high-acceleration pedestals. These arrays are
designed to withstand winds in excess of 125 mph. Dissimilar
metal junctions are eliminated in high power antennas to
improve corrosion resistance.
CPA – 042/HP
CPA-17/F1 is our high gain and very compact Helical Array
Antenna assembly for INMARSAT F1 terminals. This antenna
is intended to be used with new compact gimbals for smaller
INMARSAT Ship Earth Stations (SES). This greatly reduces
the swept volume of the marine antenna system. CPA-17/F1
(old model # 0124-800) is smaller in diameter than
conventional standard A/B SES reflector antennas but
conforms to INMARSAT F1 SDM gain, sidelobe envelope, G/T,
axial ratio and polarization requirements.

HELICAL ANTENNAS
AND RF FEEDS
3D
HQA series, Quadrifilar Helical antennas are available for
applications requiring an antenna with a broad beam
radiation pattern (half power beamwidths in excess of 145
degrees). The compact size and light weight of the HQA
series antennas are attractive for GPS applications and
INMARSAT standard C terminals.
HQA – 22R
HAS series omnidirectional Helical antennas are available
for cost-effective satellite communication links from mobile
platforms such as trucks, railroad cars, locomotives, small
boats, aircrafts, automobiles and handheld terminals.
Our innovative and patented HMA series Helical Mast
antennas provide high gain and omnidirectional coverage
with an adjustable and variable elevation beam peak range.
The elevation beam can be adjusted manually or remotely
using a motorized mechanism. A multisection mast-type
antenna
HMA-LT (Old Model 9760-800) can be easily
disassembled for storage in an 8” package for tactical
applications.
HAS – L (9520-810)
HELICAL FEEDS
HCF series circularly polarized feeds are available for use in
parabolic reflector antennas. Antenna feeds are available for
use in antennas for L-band INMARSAT standard ‘A’
terminals including feeds for antennas aboard ships (Ship
Earth Stations) and portable antennas. All feeds are used in
our high gain INMARSAT / Standard ‘A’ and ‘B’ Ship Earth
Station (SES) reflector antennas.
HMA – LR (9537-800)
Feeds are also available for GPS (L1 and L2), Ku-band DSS,
telemetry and other reflector antennas for SATCOM
applications. Special Ku band feeds are designed to retrofit
and upgrade old L-band satcom antennas.

WORLDSPACE MARITIME
APPLICATIONS
3D
The HRP-‘W’‘X’‘X’ antennas are used by
Worldspace maritime subscribers to
receive
Worldspace’s
digital
radio
programming. This new satellite service
features entertainment, weather, digital
messaging and fisheries information for
sailors.
Seavy Engineering’s omni antennas
receive the Worldspace satellite signal and
connect to the Worldspace receiver. Two
antennas (one LHCP and one RHCP) are
used to fully utilize all of the Worldspace
radio channels. Separate antenna model
numbers are used for Atlantic and
Mediterranean maritime areas.
These antennas can be easily installed on small boats, yachts and commercial vessels.
Because of their 360-degree omni-directional azimuth pattern and broad elevation coverage,
they will receive the Worldspace signal in all but extreme boat motions.

SPIRAL ANTENNAS
CONICAL LOG SPIRALS
Our CLS series antennas are compact, moderate gain conical
log spirals designed to transmit and receive signals over a
broadband. CLS antennas are available for left or right
circular polarization. The customer should specify the desired
polarization when ordering the antenna. These antennas are
also capable of receiving signals in both linear and circularly
polarized fields. CLS antennas are ideally suited for use in
anechoic chambers and enclosures where space is at a
premium and isolation is critical.
CLS-2010/A
Standard CLS antennas are intended for relatively permanent
installations. The antenna cone is supplied with a mast, which
can be mounted on any tripod with a 1/4-20 stud. CLS
antennas may be supplied with special mounting holes in the
base plate for end mounting.

SPIRAL ANTENNAS
3D
CAVITY BACKED SPIRALS
Our CBS series cavity backed spirals are
broadband antennas designed for ECM,
surveillance, direction finding, telemetry, and
flush mounted airborne applications. These
spirals can be used as a separate component
antenna or as broadband feeds for reflector
type dish antennas.
All CBS series spiral antennas exhibit an
excellent impedance match and radiation
pattern control over the broad operating bands
in a compact and lightweight package. These
spirals are ideally suited for amplitude matching
and phase or gain tracking. The unit-to-unit
uniformity
and
frequency
independent
performance is ideal for airborne monitoring
receiving systems. All cavity-backed spirals are
available in RHCP or LHCP. These spirals
have been designed to operate in a harsh
environment and meet the extremes of the
MIL-E-5400 Class 2 specification.

SPIRAL ANTENNAS
3D
EQUI-ANGULAR SPIRALS
Our equi-angular spiral antennas are designed for
impedance and pattern characteristics, which are
essentially independent of frequency over the design
range. These antennas are ideal for search applications
where the polarization of the signal is unknown and/or
where freedom from multipath interference effect is
desired. The beam is right-circularly polarized on axis off
one face, and the left-circularly polarized off the other.
The pattern goes to zero in the plane of the spiral.
ESA-3/B
The ESA-220/A and ESA-3/B are suitable for indoor
applications and may be used for low power transmitting.
The construction is such as to minimize size and weight,
and it can be rolled or folded for ultimate portability. The
antenna is fed at the center by a miniature coaxial cable.
The ESA-330 antenna is available with a lightweight
protective radome.
